Abstract
On the basis of the solution of the diffraction problem, the effective permittivity of the composite material consisting of alternating planar lattices of resistive squares displaced relative to each other and located in the dielectric layer is calculated. It is shown that the dispersion has a relaxation character. It is shown that it is possible to vary the dispersion characteristic over a wide range by varying the parameters of the structure. It is shown that the mutual displacement of lattices significantly changes the dispersion of the dielectric constant of the structure. The ratio of the wavelength to the period of the structure is estimated, at which the homogenization procedure is adequate.
